Title: Air conditioning system of negative pressure type special facility
Inventor: KIM DONG GI
IPC: F24F13/28
Filed: 2018-07-26
Abstract: Disclosed in the present invention is an air conditioning system of a negative pressure type special facility, wherein an air supply hole and an air discharge hole are installed at each chamber composed of a locker room, a shower room, a waiting room, and an experiment room. Therefore, each air supply hole and an air conditioner are connected through a main air supply pipe, such that air may be supplied to each chamber through the air supply hole by the operation of the air conditioner. In addition, each air discharge hole and an air discharge fan motor are connected through a main air discharge pipe, such that the air may be ventilated from each chamber by the operation of the air discharge fan motor. Accordingly, each chamber maintains a negative pressure state, while a differential pressure is formed between the chambers. Here, an air supply motor damper is installed on an air supply branch pipe which connects the main air supply pipe to each air supply hole, and an air discharge motor damper is installed on an air discharge branch pipe which connects the main air discharge pipe to each air discharge hole. The air discharge motor damper is operated in a constant air volume control method which fixes an opening rate, and the air supply motor damper is operated in a variable air volume control method. Moreover, a pressure measuring sensor is installed to connect a pressure measuring line individually connected to each chamber to an air pipeline connected to outdoor air. Resultantly, the absolute differential pressure value of each chamber compared to the atmospheric pressure is measured by means of the pressure measuring sensor, and the opening rate of the air supply motor damper is controlled in order to maintain the uniform differential pressure between the chambers according to the measured absolute differential pressure value.
